True. This is a slippery slope. As soon as we start offering money for an oversold flight, people are going to take full advantage of this. This quickly becomes a big money loser for us.

Perhaps someone should put forth legislation that prevents all airlines from over booking. It would be a level playing field, all airlines just charge more to compensate for the losses of not over booking. As an exception to the law, PS could be added after the flight is sold-out, up to a certain percentage. In this scenario we could then legally offer people money to take a later flight. Just thinking out load, I'm sure there is some reason this can't work.
